Description
PA0~PA7
I/O
Wake-up
Pull-high*
CMOS or Schmitt
Input
Bidirectional 8-bit input/output ports
Each bit can be configured as a wake-up input by options. Software instruc-
tions determine theCMOSoutputorSchmitttriggerorCMOSinputwithorwith-
out pull high resistor (by options).
PB0~PB7
I/O
Pull-high*
Bidirectional 8-bit input/output ports
Software instructions determine the CMOS output or Schmitt trigger input
(pull-high depends on options).
VSS
Negative power supply, ground
INT
I
External interrupt Schmitt trigger without pull high resistor
Edge trigger is activated during high to low transition.
TMR0
I
Schmitt trigger input for Timer/Event Counter 0
TMR1
I
Schmitt trigger input for Timer/Event Counter 1
PC0~PC7
I/O
Pull-high*
Bidirectional 8-bit input/output ports
Software instructions determine the CMOS output or Schmitt trigger input
(pull-high depends on options).
RES
I
Schmitt trigger reset input, active low
VDD
Positive power supply
OSC1
OSC2
I
O
Crystal
or RC
or RTC
OSC1andOSC2areconnectedtoanRCnetworkoracrystal(byoptions)for
the internal system clock. In the case of RC operation, OSC2 is the output
terminal for 1/4 system clock.
These two pins also can be optioned as an RTC oscillator (32768Hz). In this
case, the system clock comes from an internal RC oscillator whose fre-
quency has 4 options (3.2MHz, 1.6MHz, 800kHz, 400kHz)
PD0~PD7
I/O
Pull-high*
Bidirectional 8-bit input/output ports
Software instructions determine the CMOS output or Schmitt trigger input
(pull-high depends on options).
PE0~PE7
I/O
Pull-high*
Bidirectional 8-bit input/output ports
Software instructions determine the CMOS output or Schmitt trigger input
(pull-high depends on options).
PF0~PF7
I/O
Pull-high*
Bidirectional 8-bit input/output ports
Software instructions determine the CMOS output or Schmitt trigger input
(pull-high depends on options).
PG0~PG7
I/O
Pull-high*
Bidirectional 8-bit input/output ports
Software instructions determine the CMOS output or Schmitt trigger input
(pull-high depends on options).
Note:
* The pull-high resistors of each I/O port (PA, PB, PC, PD, PE, PF, PG) are controlled by an option.
CMOS or Schmitt trigger option of port A is controlled by an option.
